This project is a simple client example for CRAES, which can be found here. It reads CSV files of arbitrary complexity, parses and sends them to a running CRAES instance and parses the response from the exchange.

This project assumes Python 3.7+. This is not a hard requirement on the exchange side but comes from asyncio. The easiest way to use this client is by using poetry (see here). Assuming you are using poetry, you can run the client with

git clone 
cd craes_pyclient
poetry install
poetry run client

In case you do not want to use poetry, install the packages listed in pyproject.toml under the entry [tool.poetry.dependencies].

The client provides a CLI:

$ poetry run client --help
Usage: client [OPTIONS]

Options:
  --server_addr TEXT     Address CRAES is listening on
  --server_port INTEGER  Port CRAES is listening on
  --user_name TEXT       User name to authentificate with
  --passphrase TEXT      Passphrase to authentificate with
  --file TEXT            CSV file with orders to be sent
  --help                 Show this message and exit.

All arguments have default values that point towards a local instance with the test_user setup, sending the order file orders.csv commited in the repository.

For quick debugging and experimenting with the protocol, this package also provides a test server, which can be launched with poetry run testserver. This starts a WebSocket endpoint on the local machine which accepts orders, prints them to STDOUT and responds with an empty trade response.
